0.46” imby/Columbia as rain winds down.

Intriguing line moving SSE toward Md. Storm watches issued for this afternoon.

0.08” in Sunday evening’s 15-20 min pop-up Columbia shower. 4.22” for August thru 8/30.

An uninspiring 0.20” Thursday but it did get me over 4” for August (Columbia)

Imby/Columbia 0.31” just after midnight on Sunday morning. 3.94” so far for August.

Imby/Columbia as of 6pm — 1.3” so far this afternoon, falling over 90 mins covering 2 separate cells.

A disappointing 0.11” for 8/16 imby/Columbia. 2.22” for August thru 8/16.

That cell just south or south southwest of Urbana could be on the way, close call.

In my part of Columbia at 3 PM there is a break in the action/overcast. There are about 0.11 inches of rain. Hopefully more to come.

From 8/3 thru 8/5–am received imby/Columbia 1.70”.

Wound up with beautiful afternoon weather Sunday and Monday at Assateague Island National Seashore. Surprisingly very little rain so far.

Been lucking out overnight near Berlin, Md. with very little to no rain since arriving Sunday. Excellent beach day on Sunday. Mostly overcast and humid this morning with a few peaks of sun, but dry so far. Hazardous weather statements locally for 3’-5’ waves, rough surf and rip currents.

I can confirm that.

Yes, I’ve been noticing the past two weeks that the sun is setting sooner than mid-June when it was still technically sunny just before an 8:35/8:40 sunset. It’s definitely been noticeable to me over last few weeks, so I even checked on it. Today we are losing 1:54 minutes daily in day length. Beginning August 5 we start losing two minutes of day length daily, which increases gradually over the rest of August, getting up to 2:26 minutes of lost day length by Aug 31. The rate of decreasing daylight starts slowing down, so that by the end of September we are losing “only” 2:32 minutes daily of day length.

Imby/Columbia had 6.89” for July ‘26. Highest since 9.23” in July 2025; but honorable mention goes to May 2026 with 6.29”.

I’ll be in Berlin, Md <—> Assateague. Could change or cancel reservation no later than today but decided we’re going. Sunday & Wednesday look “fairly” decent, Monday & Tuesday questionable. But not rain all the time. I’m good with only overcast skies if it doesn’t rain all day at the beach — still getting the UV rays, may feel more comfortable, perhaps less people.

Supposed to go to Assateague Sun-Wed. Looking iffy at best after Sunday.

Columbia: 0.61” imby, 6.89” for July.

Columbia: 0.61” imby, 6.89” for July.

6 PM LWX Regional Weather Roundup has Frederick reporting a temperature of 102 with a heat index of 104. It may be time to get that thermometer out of the sun.

The deep moisture was pushed way south overnight, into southern Virginia. With the main front moving in later today there is a spotty chance for someone to get a localized shower or a storm. Odds greatly favor northern Virginia/Fredericksburg area and points south/SE ….. as opposed to those of us up in the Baltimore area. Although I do notice the local forecast here/Columbia went from mostly sunny …. to 30% chance of a scattered shower/storm later in the afternoon during peak heating but that could be as much for just covering all the bases in case anything isolated pops up. Consider yourself lucky if you’re north of DC and get some rain this afternoon. Not expecting much if anything.

Columbia: Another 0.97 inches with the second wave of rain last night bringing the daily total to 1.84 inches and a little over 6 inches now for July. AQI starting the day at a “good” 41.

Columbia: 0.87” over last hour or so with very light rain ongoing. Latest storm gets me over 5” for July.

I suspect we’ll be in and out of the smoke for at least a few weeks until the Canadian fires diminish.

1.16” total imby/Columbia on July 18. —0.11” during pre-dawn t-shower —1.00” for late afternoon t-storm —0.05” Saturday evening after t-storm 4.44” so far in July.
